Sorry, the above does not make much sense as an XSLT stylesheet as you 
have not shown any xsl:template and as
   <xsl:for-each select="mainNode/subnode[$filter]">
looks wrong too. Do you have
   <xsl:for-each select="mainNode/subnode[@id = $filter]">
instead?

Which XSLT processor are you using? How do you run the transformation? 
With XslCompiledTransform and if you run the transformation with code 
you could pass in a node-set as the parameter value.
Here is an example, the C# code to run the transformation is

         static void Main(string[] args)
         {
             Test(new string[] { "id1", "id3" });
             Test(new string[] { "id2", "id4", "id5" });
         }

         static void Test(string[] ids)
         {
             XslCompiledTransform proc = new XslCompiledTransform();
             proc.Load(@"..\..\XSLTFile1.xslt");
             XsltArgumentList paramList = new XsltArgumentList();
             paramList.AddParam("ids", "", MakeIdsNodeSet(ids));
             proc.Transform(@"..\..\XMLFile1.xml", paramList, Console.Out);
             Console.WriteLine();
             Console.WriteLine();
         }

         static XPathNodeIterator MakeIdsNodeSet(IEnumerable<string> ids)
         {
             XmlDocument doc = new XmlDocument();
             using (XmlWriter writer = doc.CreateNavigator().AppendChild())
             {
                 writer.WriteStartElement("root");
                 foreach (string id in ids)
                 {
                     writer.WriteElementString("id", id);
                 }
                 writer.WriteEndElement();
             }
             return doc.DocumentElement.CreateNavigator().Select("id");
         }

the stylesheet is

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet
   version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

   <xsl:param name="ids" select="/.."/>

   <xsl:output method="xml" indent="yes"/>

   <xsl:template match="mainNode">
     <xsl:copy>
       <xsl:apply-templates select="subnode[@id = $ids]"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="@* | node()">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
     </xsl:copy>
   </xsl:template>
</xsl:stylesheet>


the XML is taken from your post, the output of the C# program is

<?xml version="1.0" encoding="ibm850"?>
<mainNode>
   <subnode id="id1">
     <someInfo>information_1</someInfo>
   </subnode>
   <subnode id="id3">
     <someInfo>information_3</someInfo>
   </subnode>
</mainNode>

<?xml version="1.0" encoding="ibm850"?>
<mainNode>
   <subnode id="id2">
     <someInfo>information_2</someInfo>
   </subnode>
   <subnode id="id4">
     <someInfo>information_4</someInfo>
   </subnode>
   <subnode id="id5">
     <someInfo>information_5</someInfo>
   </subnode>
</mainNode>

so you can see that the stylesheet outputs those someInfo elements for 
which the id attribute value was passed in as a parameter.
